Prof. Ryan Tietz Earns Ph.D.

Dr. Ryan Tietz teaches a class.

FORT WAYNE, Ind. (CTSFW)—On August 30, the Rev. Professor Ryan M. Tietz became Dr. Tietz, successfully defending his dissertation “The Deliberately Delayed Eschatological Vision: The Hermeneutical and Theological Function of Isaiah 30” and earning his doctorate from Trinity Evangelical Divinity School in Deerfield, Illinois. In his dissertation he argued that Isaiah 30 functions as a mirror text for the tension in the delay of salvation, especially in Isaiah 30:18:

Therefore the Lord waits to be gracious to you,
and therefore he exalts himself to show mercy to you.
For the Lord is a God of justice;
blessed are all those who wait for him.

Dr. Tietz’s interest in Isaiah goes back to his days as a seminarian, when he took a course on Isaiah 1-39 and discovered how “horribly complex” it is. “I’m convinced Isaiah is bad for your spiritual health,” Dr. Tietz said. “The moment I think I know what’s going on, I discover something new was meant. But seriously, I enjoy getting into the vividness and complexity of Isaiah and his eschatology. One of my biggest interests is how Isaiah moves us from creation to the new creation, and the tension of what it means to wait for God. Frankly,” he added, “that’s what I love about what I do.”

The Assistant Professor of Exegetical Theology first came to Concordia Theological Seminary (CTSFW), Fort Wayne, in 2015. He had been working in Chicago as an interim pastor and adjunct professor at Concordia University Chicago, teaching courses in Theology and Hebrew, when Academic Dean Rev. Dr. Charles A. Gieschen asked if he’d be open to an interview at the Seminary. He’s not the only one who’s happy he said yes. “He’s been a wonderful teacher in Old Testament as well as colleague,” Dr. Gieschen said of Dr. Tietz. “Along with the entire faculty, I rejoice in his successful completion of this Ph.D. program and am confident that his exemplary academic achievements will bear much fruit that will benefit our students and the wider church for many years to come.”
